Abstract

UN PROCEDIMIENTO PARA GOBIERNO DEL MOVIMIENTO DEL EMBOLO DE MANDO (22) DE UNA VALVULA DE MANDO DE AIRE (7) PARA UNA BOMBA DE DOBLE MEMBRANA FUNCIONANDO POR AIRE A PRESION SE MEJORA DE MODO QUE EL EMBOLO DE MANDO (22) SE MUEVE POR UN MEDIO DE MANDO, PRINCIPALMENTE POR AIRE Y SEGUIDAMENTE SE MANTIENE EN SU POSICION FINAL O DE INVERSION POR UN DISPOSITIVO DE SUJECCION CONTRA LA PRESION DEL AIRE DURANTE UN INTERVALO DE TIEMPO DADO O HASTA UNA CONTRAPRESION CON EL AUMENTO DE PRESION CORRESPONDIENTE. SI SE LIBERA EL EMBOLO DE MANDO (22) DEL DISPOSITIVO DE SUJECCION, SE MUEVE CON UNA FUERZA DE EMPUJE QUE ES MAYOR QUE LA FUERZA MAXIMA DE FRICCION QUE TIENE LUGAR. ADEMAS TRABAJA EL DISPOSITIVO DE SUJECCION PRINCIPALMENTE CON AYUDA DE ELEMENTOS DE CONSTRUCCION EFECTIVOS ELASTICA (35), MAGNETICA (31, 32) O ELECTROMAGNETICAMENTE (33, 34). LA VALVULA DE MANDO DE AIRE (7) ADECUADA PARA LLEVAR A CABO EL PROCEDIMIENTO CONTIENE LOS CIERRES (16, 17) CORRESPONDIENTES PARA EL AIRE DE MANDO Y SE CARACTERIZAPOR LA COLOCACION DE UN DISPOSITIVO DE SUJECCION (31, 32; 33, 34; 35, 36) FUNCIONANDO ACOPLADO POR LA MEMBRANA DE LA BOMBA (3), QUE ESTA EN CONEXION EFECTIVA ELASTICA, MAGNETICA O ELECTROMAGNETICA CON EL EMBOLO DE MANDO (22) DE TAL MODO QUE CONTRARRESTA LA PRESION DEL AIRE DE MANDO AL MENOS DURANTE UN TIEMPO DEFINIDO Y/O HASTA UNA PRESION DEFINIDA.A PROCEDURE FOR GOVERNMENT OF THE CONTROL PISTON MOVEMENT (22) OF AN AIR CONTROL VALVE (7) FOR A DOUBLE MEMBRANE PUMP OPERATING BY PRESSURE AIR IS IMPROVED SO THAT THE CONTROL PISTON (22) IS MOVED BY A MEANS OF CONTROL, MAINLY BY AIR AND THEN MAINTAINED IN ITS FINAL OR INVESTMENT POSITION BY A DETACHING DEVICE AGAINST AIR PRESSURE DURING A TIME INTERVAL GIVEN OR UNTIL A COUNTERPRESSURE WITH THE CORRESPONDING PRESSURE INCREASE. IF THE CONTROL PISTON (22) IS RELEASED FROM THE FIXING DEVICE, IT MOVES WITH A PUSHING FORCE THAT IS GREATER THAN THE MAXIMUM FRICTION FORCE WHICH IS IN PLACE. IN ADDITION, THE FIXING DEVICE WORKS MAINLY WITH THE AID OF ELASTIC (35), MAGNETIC (31, 32) OR ELECTROMAGNETICALLY EFFECTIVE CONSTRUCTION ELEMENTS (33, 34). THE AIR CONTROL VALVE (7) SUITABLE FOR CARRYING OUT THE PROCEDURE CONTAINS THE SEALS (16, 17) CORRESPONDING FOR THE CONTROL AIR AND THE CHARACTERIZATION OF THE PLACEMENT OF A FIXING DEVICE (31, 32; 33, 34; 35 , 36) RUNNING COUPLED BY THE PUMP MEMBRANE (3), WHICH IS IN EFFECTIVE ELASTIC, MAGNETIC OR ELECTROMAGNETIC CONNECTION WITH THE CONTROL SWITCH (22) IN SUCH A WAY THAT IT COUNTERS THE CONTROL AIR PRESSURE AT LEAST FOR A DEFINED TIME AND / OR UP TO A DEFINED PRESSURE.
